Content-based routing for wireless sensor network using intelligent agents

摘要

Mobile Ad hoc Networks (MANETs) and Multi-Agent Systems (MASs) are two highly active research areas in the field of computer science. In one side, MANETs provide an alternative way to wired infrastructure networks and manage the wireless communication, whereas MASs allow distributed systems to be designed and implemented in an autonomous way by optimizing the development process. Using autonomous objects provides new mechanisms for efficient processor and memory usage while enabling low-power consumption in communication. We have presented a content-based networking protocol to solve some inherent problems in wireless sensor networks, especially in communication. Content-based protocols are mainly maximized the rate of suitable message delivery and minimize the energy consumption by using techniques to maintain shortest paths. The proposed protocol sends data using agent-based platform, and each sensor can make its decision individually. This mechanism prolongs life time of the network. After some nodes die, system can automatically construct new paths for data dissemination. As an experimental work, the performance analysis and evaluations are conducted in terms of some main efficiency metrics, which are first node dies and half of the nodes alive. As an energy-aware system, the total remaining energy level also be calculated, and this metric can be used for estimating the lifetime of the system.
